G7S- @ -E 

- EN standards, VDE certified EN61810-1 (Electromechanical non-specified time all-or-nothing relays) EN60255-23 (Contact performance) 

If an NO contact becomes welded, all NC contacts will maintain a minimum distance of 0.5 mm when the coil is not energized. Likewise if an NC contact becomes welded, all NO contacts will maintain a minimum distance of 0.5 mm when the coil is energized. 

EN50205 (Relays with forcibly guided (linked) contacts)

## **Safety Precautions** 

Be sure to read the precautions for “ _Precautions for All Relays_ ” and “ _Precautions for All Relays with Forcibly Guided Contacts_ ” in the website at:http://www.ia.omron.com/. 

## **Indication and Meaning for Safe Use** 

**Indicates a potentially hazardous situation CAUTION which, if not avoided, may result in minor or moderate injury or in property damage.** 

**Precautions Supplementary comments on what to do for Safe Use or avoid doing, to use the product safely.** 

## ! **CAUTION** 

Do not pass currents of 6 A or more when using this product in combination with the P7S-14F/14P/14A Socket. Doing so may result in fire. Use this product in combination with the P7S-14F-END/14P-E. 

## **Precautions for Correct Use** 

## **Wiring** 

- Use one of the following wires to connect to the P7S-14F-END. Stranded wire: 0.75 to 1.5 mm[2] Solid wire: 1.0 to 1.5 mm[2] 

- Tighten each screw of the P7S-14F-END to a torque of 0.78 to 0.98 N·m. 

- Wire the terminals correctly with no mistakes in coil polarity, otherwise the G7S will not operate. 

- If you use the P7S-14F-END, the release time of the G7S will be longer because the P7S-14F-END has a built-in diode to absorb coil surge. Confirm operation under actual conditions before you use the P7S-14F-END. 

## **Cleaning** 

The G7S is not of enclosed construction. Therefore, do not wash the G7S with water or detergent. 

## **Mounting** 

The G7SA can be installed in any direction.
